DEVICE FOR USE IN CQNNECTION WITH VELOCITY-METERS.

Specification of Letters Patent.

Application filed July 2, 1904. Serial No. 215,204.

To all whom it may concern.-

Be it known that I, EDWARD S. COLE, a citizen of the United States,residing at Upper Montclair, in the county of Essex and State of NewJersey, have invented a certain new and useful Improvement in Devicesfor Use in .lonnection with Velocity-Meters,of which the following is afull, clear, concise, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

My invention relates to devices for measuring the velocity of flow offlowing streams; and it relates in particular to means for connectingsuch devices with the mains or pipes in which the streams are flowing.

Prominent objects of my invention are to provide a simple, practical,and inexpensive device for connecting such meters with the pipes ormains, to arrange for the ready and easy attachment of such devices tothe mains and the quick and easy detachment of the same therefrom, toadapt the device for use on large mains. and to secure the foregoing andother desirable results in a simple and expe-v ditious manner.

In the accompanying drawings, Figure 1 is a view of a connecting deviceembodying my present invention, together with a portion of a main towhich the device is attached. Fig.

2 is a view taken on line 22in Fig. 1. Figs. 3, 4, and 5 arecross-sections taken on lines 3 3, 4 4, and 5 5, respectively, in Fig. 1Fig. 6 is a detail of construction.

In Fig. 1 l have shown a water-main A, in which flows a stream of waterwhose velocity it is desired to measure. Instead of a watermain anyother pipe or main can have the device applied to it. The water-main isprovided with an aperture, and into this fits a plug 1, which isconveniently screw-threaded, so as to permit its ready attachment to anddetachment from the main A. A nut 2 is fitted to the upper or outer endof the plug 1,

and a cap 3 is fitted to the outer end of the plug 2, these parts beingrespectively screwthreaded together for convenience of connection anddisconnection. Between the plug 1 and nut2 is a washer 4. A pair oftubes 5 5 is extended through the plug 1, nut 2, and cap 3 and into theinterior of the pipe or main A. The cap 3 is provided withstuffing-boxes 6 6, having bushings 7 7, by which a watertight jointwith the tubes 5 5 is made. The lower ends of the tubes 5 5 areconstructed with bent ends 8 8, having orifices 9 9, ar-

ranged to extend longitudinally in the pipe or main A. The lower ends ofthese tubes 5 5 are connected together by a yoke or crosspiece 10, whichembraces both of said tubes. A spring 11 is secured to the yoke 10, andits outer ends are arranged to engage grooves in the tubes 5 5, as shownin Fig. 5. The tubes 5 5 are loose in the cap 3 and also in the yoke 10,so that they can be freely turned or rotated so as to cause the bentends 8 8 to face outward, as shown in full lines in Fig. 1, or to faceinward-that is, toward one another, as shown in dotted lines in saidfigure. A clamp conveniently consisting of a pair of plates 12 12 and athumb-screw 13 is arranged upon the upper ends of the tubes 5 5, so thatby adjusting the thumb-screw 13 the clamp can be tightened upon the saidtubes, so as to prevent their rotation, or can be loosened, so as topermit such rotation. \Vings or side projections 14 14 are secured to orformed upon the tubes 5 5, so that they are engaged by the clampingmembers 12 12 to assist in the clamping action and also to hold thetubes in proper position, the wings 14 14 being on the same sides of thetubes as the bent ends 9 9. The tubes 5 5 are alsodesirably providedwith clips or vanes 15 15 on the same sides of the tubes to serve ashandles to assist in turning the tubes and also as vanes or indicatorsto indicate the positions of the bent ends or orifices9 9.

A spreading device for spreading or separating the tubes 5 5 from oneanother is desirably provided. It conveniently consists of a pair ofplates 16 and 17, arranged upon the tubes 5 5 and pivoted together at18. A rod 19, having a projection 20, adapted to act upon the plate 16,is extended down through the parts 1, 2, and 3 and provided at its upperend with a handle 22, so that it can be readily turned by hand by aperson using the device.

The tubes 5 5 are connected with flexible tubes or connectors 23 23,which are understood to extend to some form of velocity measuringor.indicating device. As this device can be of any particular form orvariety and forms no part of my present invention, it is not shownherein. Another tube 24 is shown connected with a pipe 25, attached tothe cap 3, this being also provided for the recording device.

In using the device the pipe A is provided with a threaded aperture, ifsuch is-notalready provided, and then the plug 1 is screwed other downstream.

into such aperture. The connecting device is 1 upon the tubes 5 5, sothat the latter can be then attached to the plug 1 by the screwing ofthe nut 2 upon said plug, the nut 2 and cap 3 being previously screwedtogether. This attachment of the nut 2 to the plug 1 is'permitted byfirst turning the tubes 5 5 so that their bent ends 8 8 extend or faceinwardly and then inserting said ends and the lower portions of thetubes through the nut 2 and plug 1, which insertion, it will be seen, ispermitted by the fact that when the tubes are so turned their bent endsdo not project outwardly. After the tubes are thus inserted and the nut2 and cap 3 secured in position the tubes 5 5 are turned one hundred andeighty degrees, so as to cause their bent ends 8 8 to face outwardly, asshown in Fig. 1. This can be determined by the vanes 15 15. The clampingmembers 12 12 are then adjusted so as to hold the upper ends of thetubes firmly against further rotation. The spring 11 engages the groovesin the lower ends of the tubes, and thus holds these ends firmly againstrotation. The handle 22 of the rod 19 is then turned so as to cause theprojection 20 on said rod to act against the plate 16, and therebyseparate the tube 5, inclosed by said plate slightly from the othertube. This separation of the tubes tends to hold them in a rigidcondition and also tends to bind them in position in the cap 3 toprevent longitudinal movement of the tubes in said cap. In this wayafter the tubes have been inserted in position in the main they can beheld firmly and rigidly or, it may be said, can be trussed to preventtheir being bent or swung or being rotated in the main A. This isdesirable because in water-mains, especially in large mains, the flow ofWater is likely to bend or swing the tubes out of a perpendicular andtrue line or to causeaswinging or vibrating motion of the tubes in oneWay or another. This is especially likely to occur in large mains,because the tubes must be of considerable length to extend well intothose mains, and hence the tubes being of considerable length are moresubject to the force exerted by the flow of water. By my invention,however, the tubes are held firmly together and in their properpositions and do not swing or become dislocated in the main. They arealso kept edge on that is to say, the orifices 9 9 are maintained intheir desired conditions, one pointing up and the The tubes can also belocked in any position to which they are adjusted in the main-that is,in an up and down position-by spreading them, so as to lock or bind themin the cap 3.

In Fig. 1 the tubes are shown inserted only part way into the main. lVhen inserted to their full extent, their lower ends extend down muchfarther into the main and a much smaller portion remains above the cap3. The plates l6 17, it is understood, are loose inserted down to anydesired position in the main without affecting the operability of thespreading device.

It will be understood that changes and modifications can be made in thedevice herein shown Without departing from the spirit of my invention.
